Hey! I just registerd on the forum so im a newbie to the tech stuff.

I have a Ford F-150 5.4L SuperCrew and I was wondering what exhuast system will give me the most horsepower and torque? I dont mind if its loud or anything. Just what helps make the most hp/torque? oh and does it matter if its stainless steel or aluminum? thx for the help guys

 

If you can afford $500.00 you might check into Spintech. They have been proven to ad 15-20 hp and 13-17ft lbs of tq. A friend of mine put one on his 5.4 and it sounded great. He said it was more responsive than before. If you want a loud exhaust go with the Pro Street if you want it quieter go with one of their sportsman models. I will probably order a Spintech system this week if I can convince myself to spend the $500.00.
